WILLIAM C. DE WITT, OF CHICAGO, ILLINOIS.

WINDO'W-GUARD.

Specification of Letters Patent.

Patented Oct. 22, 1912.

Application filed April 5, 1912. Serial No. 688,643.

To all whom it may concern:

Be it known that 1, WILLIAM C. DE WITT, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Tmprovement in Window-Guards, of whichthe following is a specification.

My invention relates to a window guard or storm guard for windows and isillus trated in the accompanying drawings, wherein- 7 Figure 1 is across section of the window and guard showing the latter in position;Fig. 2 is a detail plan view of the guard in position with portions ofthe window casing; Fig. 3 is a reduced plan view of the guard not inposition; Fig. at is a cross section along the line ll of Fig. 3 withthe parts in their folded position; Fig. 5 is a plan view of the partsshown in Fig. t.

Like parts are indicated by the same letters in all the figures.

A, A indicate the several parts of the win dow casing and B the lowerpart of the sash. The guard consists of the body portion C with the endportions D, D and the edge portion E. The edge is provided with thegromets E E and the eyelets E The end portions are provided with grometsD D and the rods l) projecting at each end. The body portion is providedwith the eyelets C The screws F, F are provided to be attached to thewindow sill and similar screws G are adapted to be attached to thevertical part of the Window frame.

H is screw-eye, one being at each side of the window casing, and I is atape adapted at one end to fit over the end of the rod D and at theother end to be attached to the screw-eye J.

K, K are cords adapted to be laced through the eyelets E C so as toshorten the guard when desired as indicated in Figs. land 5. Theengaging screws and gromets may be of any desired character butpreferably so as to permit gromets to be sprung or forced over the headsof the screws and yet to remain in such secured position. Of course, thescrews can be removed to disengage the guard if provided with removableheads or if made for the purpose of securing the guard in a relativelypermanent manner.

The use and operation of my invention are as follows: The guard, shapedas shown,

may be cut from a single piece or strip of flexible material so as toleave no seams. It is preferably made of opaque canvas pervious to airbut of such a shade, for example olive green, as to exclude the light.To attach it, the Window is raised as indicated in Fig. l, the gromets EE are inserted over the heads of the screws F, F, or the parts areotherwise screwed, the ends D, D are folded up into a vertical positionas indicated in Fig. 2, the inner ends of the rods are inserted each ina screw-eye, the tapes are attached one to the outer end of one of therods D and the body of the guard is then drawn up into the positionindicated in Fig. l and the tapes secured so as to hold the parts inthis relation. The lower end of the inner edge'of the portions D, D ofthe guard can then be attached by means of the gromets D D and thescrews G and the window can then be adjusted to any desired positionalong the vertical edge of the part D of the guard. The result is thatthe light is excluded by this easily detachable and removable guard andthe wind tending to come in through the open window is upwardlydeflected by the body of the guard and compelled to pass through acontracted aperture, for the distance from the lower sash of the windowto the body of the guard along a line at right angles thereto is alwaysless than the vertical distance from the lower edge of the sash to thewindow sill. This deflecting of the wind and contraction of the passagethrough which it moves results in retarding the wind, while at the sametime the guard being made of air-pervious material, lets the air passthrough it along its body and particularly at the contracted portion.This results in changing the direction of the wind so that it passesinto the room upwardly, reducing its velocity, and as it passes throughthe contracted passageway and past the point of deflection the dust,dirt, moisture, sand and the'like are taken from it, some portion of theair passing through the air pervious body guard while the wind is thusbeing deflected and forced through a contracted passage.

It is the cooperation with the air-pervious body of the guard of thewind deflecting action or the contraction of thepassage or both whichresults in cleaning of the wind which enters the room from beneath thewindow. The device being made of flexible material can be easily removedor applied and stored when desired.

By means of the eyelets E C and the cords K, K the guard can beshortened to make it suitable for windows of difierent width. Thislongitudinal adjustability can be efiected in various ways. I have onlyshown one.

I claim:

1. A window guard consisting of a flexible fabric strip havingtriangular end members, rods mounted one on either end of said stripalong one side of said triangular end members, a flap projectingdownwardly from said strip on the side opposed to said )lOClS, means forattaching said flap to a window sill, means for attaching the inner endsof said rods removably to the casement and means for drawing said rodsupwardly and outwardly against the tension of said fabric to hold themin a substantially horizontal position. I

2. A window guard consisting of a flexible fabric strip havingtriangular end members, rods mounted one on either end of said stripalong one side of said triangular end members, a flap projectingdownwardly from said strip on the side opposed to said rods, 1 eans forattaching said flap to a window sill, means for attaching the inner endsof said rods removably to the easement and means for drawing said rodsupwardly and outwardly against the tension of said fabric to hold themin a substantially horizontal position and means for varying the lengthof said strip.

side of said triangular members, means for V attaching the inner ends ofsaid rods tothe window casement and means for drawing the outer ends ofsaid rods upwardly and outwardly against the tension of the fabric tohold the guard in position. 5

4. A window guardcomprising an inclined fabric portion projectinginwardly and upwardly from the window aperture, a flap mounted on thelower end of said portion, means for removably attaching said flap tothe window sill, triangular end members projecting upwardly andoutwardly from said body p0rti.on,'rods carried on one side of saidtriangular members, means for attaching the inner ends of said rods tothe window casement and means for drawing the outer ends of said rodsupwardly and outwardly a ainst the tension of the fabric to hold theguard in position and means for varying in unison the length of saidbody piece and said flap to-provide for windows of varying widths.
